If you accelerate relative to an object in an inertial frame, you are observing the object from a non-inertial reference frame. A reference frame that moves with constant velocity relativ ...

... ●We used this formula when we looked at mass defect in nuclear energy problems. It is the energy of a mass m0 in its rest frame. ●We call m0 the rest mass or the proper mass. The rest mass is an invariant. PRACTICE: A nuclear power plant converts about 30. kg of matter into energy each year. How man ...

... The motion of particles and rigid bodies is governed by Newton’s law. In this section, we will derive an alternate approach, placing Newton’s law into a form particularly convenient for multiple degree of freedom systems or systems in complex coordinate systems. This approach results in a set of equ ...

Equation 5.1 tells us that if the net force on a body is zero, the body’s acceleration a = 0. If the body is at rest, it stays at re ...
